Adding the dealer's hand

Going on with the actual game functions, it's about time we create and show the dealer's hand, we can just copy paste what we have from the player's hand, let's start by adding the dealer's hand to our state:

struct IcedTwentyOne {
    deck: Deck,
    player_hand: Hand,
    dealer_hand: Hand,
}

And start the dealer's hand the same way we did for the player's:

impl Default for IcedTwentyOne {
    fn default() -> IcedTwentyOne {
        let mut deck = Deck::new();
        let mut player = Hand::new();
        let mut dealer = Hand::new();
        deck.shuffle();
        player.push(deck.deal_card().unwrap());
        player.push(deck.deal_card().unwrap());
        dealer.push(deck.deal_card().unwrap());
        dealer.push(deck.deal_card().unwrap());

        IcedTwentyOne {
            deck: deck,
            player_hand: player,
            dealer_hand: dealer
        }
    }
}

And now that the state is there, we can show it on our view() just like the player's hand:

fn view(&self) -> Element<Message, iced::Renderer<theme::TwentyOneTheme>> {
    let mut dealer_row = Row::new();
    for card in &self.dealer_hand.cards {
        dealer_row = dealer_row.push(image(String::from("img/") + &card.get_id() + ".png").height(Length::Fixed(250.)));
    }

And add the dealer's info to the table_col too, again, just like we did the player's, including also the hand value:

    let table_col = col![
        text(self.dealer_hand.value().to_string()).size(35),
        Rule::horizontal(4.),
        dealer_row,
        player_row,
        Rule::horizontal(4.),
        text(self.player_hand.value().to_string()).size(35),
        button(text("Deal another card")).on_press(Message::DealCard),
    ].align_items(iced::Alignment::Center).spacing(10);
